The invention'relates to devices'for facilitating copying by typists and has reference more particularly to a line reader which will render visible asingle line of the copyfuntil adjusted to bring into view the next line.` l

Anobject of the invention. is toprovide a device that will be noiseless when line spacing, that ycan be y readilysuspended from Aa suitable support, and one that will take upA very little space whenin use or when stored.

Another object isthe' provisionof a copy holder and line readerl that can be operated for spacing purposes lsimultaneously with the typewriter, thus saving valuable time andwhich can be located in the most desir-` able position `for the Vtypist.

With these and various :other objects in view, the invention may consist of certain novel features of construction and operation, asjwill be more fully described and particu-- larly pointedout in the specification, drawing and claims appended hereto.

Figure 4 is a Nfragmentary sectional view 'showing theconstructionv of one end of the main roller, and i Figure 5 is a fragmentary sectional view showing a'modiied construction of the other endof the roller.

The embodiment of the device shownin the r drawing consists essentially of a sectional shield having an upper section 10 of arcuate contour as shown in Figure and a lower section 11 also of arcuate contour, and having a curved dependinglip 12. The sections f are pivotally secured together at their adjacent edges by spaced co-operating lugs 13, formed on the sections respectively, which lugs 4are connected by the pivot shaft 14. The pivoting means for the sections are lo- 1932. Serial No. 623,252.
